I updated to CSSU-T a few days ago via HAM. HAM updated Kernel-Power to v49. Then I installed batterypatch and autodisconnect (this improved battery life a lot) and I did activate the Hardware acceleration in /etc/powervr.d/hildon-desktop.ini
So far I have no problems or errors with the latest CSSU-T ! I noticed that the occasional crashes of modest vanished. My N900 runs better and smoother than ever before. Good job CSSU Team !
